Welcome to the RH forums Mazis.
Can you start by telling us what your output is? Is it CHM? Also are you refering to the three tabs on the left (Contents, Index, Search)? If so, you just need to ensure the "Hide nav pane on Startup" option is selected in your window.

My own guess is that you are creating WebHelp output as this is the only output I'm aware of that will open in this fashion.
My second guess is that you have enabled the option for Section 508 output. This output is intended to be optimized for visually impaired users that use screen reading applications to interact with the computers.
Unfortunately I cannot divine exactly what version of RoboHelp you are using. Generally speaking, you configure the Section 508 option by editing the Single Source Layout recipe.
